Abstract
An encapsulation method of organic electroluminscence device is provided. An organic electroluminescent device is formed on an indium-tin-oxide glass substrate. A metal electrode is formed on the organic electroluminescent device. The organic electroluminescent device is encapsulated by a nitride layer or a carbide layer formed by using segmental sputtering at a low temperature. The substrate is soldered on a metal plate and covered by a metal cap.
